The Science Behind Seaborg’s Discoveries

Seaborg’s work revolutionized our understanding of the periodic table. His research focused on transuranium elements—elements heavier than uranium—expanding the boundaries of chemistry. By bombarding uranium with neutrons, he and his team synthesized new elements, proving their existence through meticulous experimentation.

Breakthrough Techniques

Seaborg employed innovative methods, including:

• Neutron capture to create heavier isotopes


• Chemical separation to isolate new elements


• Radiation detection to confirm elemental properties

Seaborg’s Impact on Modern Energy

The discovery of plutonium was a game-changer for energy production. Today, nuclear power generates about 10% of the world’s electricity, with plutonium playing a critical role in reactor fuel. Seaborg’s work laid the foundation for sustainable energy solutions, reducing reliance on fossil fuels.

Nuclear Energy by the Numbers

• 440+ nuclear reactors operate globally, powering millions of homes


• Nuclear energy produces zero carbon emissions, aiding climate goals


• The U.S. alone generates over 800 billion kWh annually from nuclear power
